T. dcsiiipta has been considered the o of T. crocata, but such 

 is not the case as I have a 9 crocata similar to the (j^, and very 

 different from dcscriptiis. T. ciiigii/ata is probably T. trilineata of 

 which T. zo/iaria appears to' be but a variety, T. iiiannorata may 

 be the same as T. ornata. 



Our genera of DictynidcX may be distinguished thus: 



\ Eyes 6 Neophanes 



\ Eyes 8 2 



2 \ Legs without spines, cribellum, undivided ..... 3 

 { Spines on some legs, cribellum divided ...... 4 



\ A. M. E. very much smaller than the others . . . Prodalia 



3 ' 



/ A. M. E. equal in seize to the others Dictyna 



\ Maxillie inclined over the lip Amaurobius 



/ Maxillre straight TitancEca 



Tapinopa, a genus related to Linyphia but differing from all 

 other Liiiyphinae in lacking spines to the legs, occurs in the 

 eastern U. S. It may be described as follows: 



Tapinopa bilineata n. sp. 



Length 9 3-5 ^^i"^- Cephalothorax pale with a broad black stripe each 

 side, which does not, however, reach the margins; mandibles yellowish, with a 

 spot at base in front and a line at base on the side blackish; sternum brown, 

 blackish on the edges; legs and palpi whitish, a broad band on middle of femur, 

 patella, bands at middle and tips of tibia and metatarsus, black; two black bands 

 on palpi. Abdomen- pale, grayish brown, blotched with white, two rows of four 

 spots above, tip with a few chevrons, sides with some oblique stripes, and ven'er 

 almost wholly, black. Legs r, 4, 2, 3. Head slighthly projecting in front over 

 the mandibles which are obliquely retreating, of large size, and have their lower 

 margins aimed with a row of slender spines. Clypeus low. A. M. E. the largest, 

 other eyes about equal; A. ^L E. projecting forwaid and downward on tubercles. 



This species lives among grass or leaves close to the ground. 

 It resembles Stcnionyp/iantcs bncculcntiis but readily separated by 

 the absence of spines on legs, the structure of its mandibles, and 

 the two rows of spots on the dorsum. The ei')igynum jirojects 

 slightly as is common in Bat/iyp/ia/i(<s. I have it from Sea Cliff, 

 N. Y. and Washington, 1). C.
